A study was conducted to replicate and extend a finding by Wheeler and Levine [1967] indicating that a dissimilar model was more effective in inducing the contagion of aggression than a similar model. On the basis of recent findings suggesting the circumstances under which dissimilar others are more influential than similar others, the following predictions were derived: When subjects are highly instigated, dissimilar models can influence subjects to be more aggressive than can similar models; when subjects are under a low degree of instigation similar models will influence subjects to be more aggressive. Subjects presented their point of view on a case study in a three-person group discussion setting. Then subjects heard the second person (instigator) attack their position in a highly abusive or slightly abusive manner (High vs Low Instigation). Next subjects heard a third person, whom they had been led to believe was similar or dissimilar to themselves, attack the instigator (Similar vs Dissimilar Model). Finally subjects had an opportunity to express their feelings to the instigator. The results supported the predictions. 相似文献

Small bilateral electrolytic lesions placed just posterior of the ventromedial hypothalamic nucleus cause a strong increase in offensive behavior. The histology suggests that damage to the ventral premammillary nucleus is responsible for this effect. A summary of the neuroanatomical literature shows that this structure is connected to most other brain structures reported to be involved in offensive behavior. 相似文献

Eysenck's Psychoticism, Extraversion and Neuroticism (PEN) Inventory was used to explore the role of personality variables in augmented personal space required by assaultive offenders. For both violent (n = 20) and nonviolent (n = 20) subjects personal space was greatest from a rear approach. Neither personality scores nor nature of offense alone predicted personal space needs; however personal space was significantly elevated in all directions for assaultive offenders with high scores on the psychoticism scale of the PEN Inventory. 相似文献

This review deals with possible central and peripheral effects of androgens upon primate aggressive behavior. One problem that clouds interpretation of experimental work is that measurements of dominance have often been employed, such as competition tests for food and water. Such measures often do not correlate with those obtained by quantifying aggressive interactions. It should be remembered that very few of the 188 primate species have been studied experimentally and that great behavioral and physiological diversity occurs within the order. Therefore, generalizations about the effects of androgens upon aggressive behavior in primates (including man) should be made with caution. Testosterone has an organizing influence upon the foetal brain of rhesus monkeys and may affect the development of neural mechanisms which govern aggression in males. More data are required on primates, however, since rhesus monkeys show some important differences from rodents as regards the effects of androgen upon sexual differentiation of the hypothalamus. In future, marmosets may provide a suitable model for such studies, because there is evidence that sexual differentiation of brain by androgen occurs postnatally in these monkeys. At puberty, male primates show a variety of behavioral changes and, during adulthood, males of seasonally breeding species may be more aggressive during the mating season, when testosterone levels are maximal. This does not indicate a causative relationship between testosterone and aggressive responses, because castration and androgen treatments have little effect upon aggression in prepubertal or adult males of several primate species. Androgens have pronounced effects on sexual responses in adult male monkeys, but their central effects upon aggression are much less important than among rodents. Elec trical stimulation of hypothalamic pathways has been employed to evoke aggressive behavior in marmosets and rhesus monkeys. In the rhesus, preliminary evidence indicates that such pathways show some sensitivity to androgens. In rodents it is known that these areas are richly supplied with monoaminergic neurons, which play an important role in aggressive behavior. There is little evidence on primates, however, and this remains a crucial topic for future research. Peripheral effects of androgens should also be considered. Many prosimians and New World monkeys use scent-marking behaviors and, in males, androgen-dependent chemical cues may be involved in sexual recognition and territorial behavior. This possibility awaits investigation. Finally, plasma testosterone levels may alter as a function of aggression itself; thus levels decrease if male rhesus monkeys are defeated by conspecifics. This might occur because neural events associated with giving (or receiving) aggression also influence pituitary function and hence alter gonadal testosterone secretion. Theoretically, it is possible that such changes in circulating testosterone might affect aggressive behavior via a feedback action on the brain, but the experimental evidence does not support such a view. 相似文献

为探究留守儿童心理虐待与攻击行为之间相关关系,采用修订后的儿童心理虐待量表、留守儿童心理弹性问卷、SCL-90中的人际关系敏感分量表和Buss-Perry攻击行为量表对754名留守儿童进行调查。结果发现:(1)心理虐待对留守儿童心理弹性具有显著负向预测作用,对人际敏感和攻击行为具有显著正向预测作用。(2)心理弹性和人际敏感分别在心理虐待与攻击行为之间起到部分中介作用。(3)心理弹性和人际敏感在心理虐待与攻击行为之间起到链式中介作用。 相似文献

通过对重庆某综合大学大一到大三527名学生的问卷调查, 运用结构方程模型技术考察了特质愤怒、敌意认知、冲动性水平和攻击行为之间的关系。结果发现:(1)敌意认知在特质愤怒和攻击行为之间起部分中介的作用, 特质愤怒既对攻击行为产生直接影响, 也通过敌意认知对攻击行为产生间接影响;(2)运动冲动性因子对敌意认知的中介作用起到调节作用, 即敌意认知对攻击行为的影响随着个体冲动性水平的增加而提升;敌意认知对个体的攻击行为起着有调节的中介作用。 相似文献
